Plant Description:

"Poison ivy can appear as a ground cover, a shrub, or as a vine growing up a tree. It likes to grow in places where it is moist. Older vines are covered in fibrous roots resembling hair that grow into the supporting tree. It has dull or glossy compound leaves on a long stem that are divided into 3 leaflets.

The name Poison Oak is often applied to the shrub-like forms of Poison Ivy. Poison Oak of the southeastern United States has its leaves divided into three leaflets; the leaflets are densely haired and generally have three to seven distinct lobes. The white, berry-like fruits are also somewhat hairy. Poison oak contains poisonous substances that are believed to be identical or closely related to that found in Poison Ivy.

Poison sumac is a shrub or small tree, up to nearly 30 feet in height, with 7-13 leaflets per pinnate leaf. These are oval to oblong; tapering to a sharp point; and wedge-shaped at the base. Leaves are wavy-edged; hair-less or slightly down-like hair on the underside, and usually 2-4 inch long. Its flowers are greenish.
